Abstract: A conductive layer for a thin film transistor (TFT) array panel includes a multi-layered portion defining a source electrode and a drain electrode of a TFT device, and includes a first sub-layer, a second sub-layer, a third sub-layer, and at least one additional sub-layer. The third and the first sub-layers include indium and zinc oxide materials. An indium to zinc content ratio in the first sub-layer is greater than that in the third sub-layer. An indium to zinc content ratio in the additional sub-layer is formulated between that in the first and the third sub-layers. The content ratio differentiation between the first and the third sub-layers affects a lateral etch profile associated with a gap generated in the second conductive layer between the source and the drain electrodes, where the associated gap width in the third sub-layer is wider than that in the first sub-layer.

Abstract: A control system includes a switch circuit, a buffering circuit, and a motherboard. The switch circuit is configured to output a switch signal having a trigger time. The buffering circuit determines whether the trigger time of the switch signal is equal to a predetermined time. If the trigger time of the switch signal is equal to the predetermined time, the buffering circuit outputs a signal to the motherboard. The motherboard performs a power off operation.

Abstract: An electronic device includes a power-saving mode and a normal mode. When a mechanical button is in a first position, a main control chip outputs a logic high pulse to a switch connected to a voltage converter, such that the switch is turned on, and the voltage converter is disabled. The electronic device accordingly enters the power-saving mode because power from an external power source cannot be converted to a work voltage of the electronic device via the voltage converter. When the mechanical button is in a second position, the main control chip outputs a logic low pulse to the switch, such that the switch is turned on, and the voltage converter is enabled. The electronic device accordingly enters the normal mode because power from the external power source can be converted to the work voltage of the electronic device via the voltage converter.

The photochromic layer is a titanium layer doped with metal element ‘M’. The element ‘M’ is selected from a group consisting of nickel, iron, and chromium. A method for applying the photochromic layer to the substrate is also described.

Abstract: A fan rotation speed test device connected to a computer includes an information processing chip, an indicating unit, and an interface. The interface is compatible with a memory socket on a mainboard of the computer. The computer transfers control instructions to the information processing chip via the interface. After receiving the control instructions, the information processing chip outputs PWM signals by executing programs therein to modulate the rotation speed of a fan. The information processing chip collects rotation speed signals of the fan, then judges if the rotation speed of the fan is according to a predetermined standard by executing arithmetic programs. The information processing chip outputs test result signals to the indicating unit for display.

Abstract: A touch input method includes steps: controlling one of the infrared emitters to turn on and send an infrared signal to the infrared receivers in sequence, thus forming a number of first infrared lines. Detecting whether an infrared receiver does not receive the infrared signal. Determining if the first infrared line is blocked by an object, thus determining a first blocked infrared line. Controlling the other infrared emitter to turn on and send the infrared signal to the infrared receivers, thus forming a number of second infrared lines. Determining if the second infrared line is blocked by the object, thus determining a second blocked infrared line. Determining touch position according to the first and the second blocked infrared lines, executing the function of a GUI element corresponds to the touch position. The disclosure also provides an electronic device with an infrared touch panel.

Abstract: A wireless communication service system and a mobile phone are provided. The mobile phone generates a calling signal of a recipient number and determines whether a storage unit has stored a cornet associated with the recipient number. If the storage unit has stored the cornet, the mobile phone sends a transmission containing the cornet. If the storage unit has not stored the cornet, the mobile phone sends a transmission containing the recipient number. When the wireless communication service system receives the transmission containing the recipient number, the wireless communication service system determines whether the recipient number has joined a cornet cluster network of a caller number. If so, the wireless communication service system calls the cornet. If not, the wireless communication service system calls the recipient number.
